NKX,NKX Z系列組合軸承
滾針組合軸承
Combined Needle Roller And Thrust Ball Bearings
NKX
NKX…Z 系列
此組合式軸承除承受徑向負荷外可承受單向軸向重負荷。
組合軸承是我司具有特色的一款產品，具有精度高，使用壽合長等特點．目前我司生產的組合軸承已于國內多個主機廠家配套并遠銷國外． 組合式滾針軸承是由一個向心滾針軸承和一個推力 軸承 相結合 ,因此能夠承受徑向和軸向負荷。 組合式滾針軸承在很小的徑向空間里對固定端 軸承 配置進行定位。...而其它類型的固定端 軸承 占空間太大的場合,這些 軸承 特別有用 ．
TN=塑料保持架，允許工作溫度：120°C連續(xù)；180°C短期。
